Hi friends. Sometimes my hobby band (www.facebook.com/therulend) plays small gigs as a three piece sans lead guitar (our guitarist lives 2 hours away). I'd like to do some things like U2's With or Without You using the BN3 looping feature playing the bass line (which is the same four notes over and over and over and over again) while playing lead guitar on the song. But (1) I can't really figure out how to use the looper in general even after searching the TalkBass threads and (2) not sure if I could prerecord the loop at home and then have it ready to go to play on stage live with me on lead. Any help appreciated.
